Overview
The SN65LBC184D is a differential data line transceiver produced by Texas Instruments. This component is designed in the trade-standard footprint of the SN75176 and features built-in protection against high-energy noise transients. This enhances reliability and provides better immunity to noise transients coupled to the data cable. The SN65LBC184D is suitable for applications requiring a reliable, low-cost, direct-coupled data line interface without the need for external components or isolation transformers.
